New
Zealand cave weta biodiversity (Rhaphidophoridae)

New Zealand cave weta are a diverse group,
falling into 16 genera and approximately 55 species. The exact number of
species is difficult to assess as many are yet to be discovered and described. Our
research focuses on developing morphological tools to diagnose genera and
species, using large samples that encompass the full variation within
populations and species. Characters that
will distinguish genera and species are best if they can be applied to
juveniles and adults of either sex. Using DNA sequencing, we will be able to
ensure that the morphological traits we focus on are effective in identifying
and distinguishing species. Here we present an example of cave weta sampled
from the Far North where we see how combining sub-genital plate shape and spine
counts can reliably differentiate species in all individuals except early
instar stages.
